Benefits of technology
[0007]Therefore, an object of the invention is to provide an error detection method for a computer system that is efficient.
[0012]enabling the keyboard controller to transmit the hardware status information received thereby to the error-detecting computer through the communication interface.
[0021]In the error detection method for a computer system according to the invention, the error-detecting computer, being provided with the hardware status information of the computer-under-test (electronic device), can determine easily a point in a boot process of the computer-under-test (electronic device) at which an error occurs. Time spent searching for the error is thus reduced, and the error detection is made more efficient. Moreover, hardware of the computer-under-test (electronic device) does not need to be altered to accommodate the error detection method of the invention, since through low-level access provided by the keyboard controller, the hardware information status can be obtained from the BIOS and used for purposes of error detect ion and system analysis.
Problems solved by technology
A notebook computer in an initial stage of development often fails to boot normally.
However, the above-described error detection method only displays a last successfully executed portion of the boot process of the notebook computer, and therefore does not provide a precise indication of a point in the boot process at which the error occurs.
Consequently, the error must be found through a process of trial and error, making the current error detection method inefficient.

Embodiment Construction
[0025]FIG. 1 illustrates an embodiment of an error detection method that is performed on a computer system in an initial stage of development. In this embodiment, an error-detecting computer 10 obtains internal information from the computer system or computer-under-test 20 in order to perform system error detection on the computer-under-test 20.
[0026]In some embodiments, the error-detecting computer 10 and the computer-under-test 20 are each provided with an RS232 compatible Universal Asynchronous Receiver / Transmitter (UART) port (which can be either wired or wireless). Through the UART communication interface established between the two UART ports, the error-detecting computer 10 can issue commands and transmit data to a keyboard controller 21 of the computer-under-test 20.
[0027]Referring to FIG. 2, a flow chart of an embodiment of an error detection method for a computer system is shown to comprise the following steps:
[0028]In step S1, the error-detecting computer 10 issues an err...

An error detection method for a computer system includes the steps of: enabling an error-detecting computer to communicate with a keyboard controller of a computer-under-test through a communication interface; enabling the error-detecting computer to issue an error detection command to the keyboard controller that causes the keyboard controller to issue a request command to the basic input / output system (BIOS) of the computer-under-test; enabling the BIOS, in response to the request command, to access the keyboard controller and determine hardware status information that is being requested from the error detection command, and subsequently, to obtain the hardware status information of the computer-under-test, and to transmit the hardware status information to the keyboard controller; and enabling the keyboard controller to transmit the hardware status information received thereby to the error-detecting computer through the communication interface.
Description
CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims priority of Taiwanese application no. 097114626, filed on Apr. 22, 2008, which is incorporated herein by reference in its entirety.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]This invention relates to an error detection method for a computer system, more particularly to an error detection method for a computer in an initial stage of development.[0004]2. Description of the Related Art[0005]A notebook computer in an initial stage of development often fails to boot normally. To find the cause of boot failure, it is necessary to perform error detection on a boot process of the notebook computer, which currently involves using a Low Pin Count (LPC) or a Peripheral Component Interconnect Express (PCIe) error detection card to read and display a status of the boot process.[0006]However, the above-described error detection method only displays a last successfully executed portion of the boot process of t...
